Long-running couples that fans thought would last forever, like Channing Tatum and Jenna Dewan, revealed their devastating breakups this year. Other stars weren't dating for too long, but their breakups were still surprising.

"Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly," read the statement given to The Associated Press by Aniston's publicist, Stephen Huvane. "Whatever else is printed about us that is not directly from us, is someone else's fictional narrative. Above all, we are determined to maintain the deep respect and love that we have for one another."

"We fell deeply in love so many years ago and have had a magical journey together," they said in a statement. "Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now."

Logic and Jessica Andrea

The rapper and his wife of two years stunned fans when they shared their amicable split in March. What's even more heartbreaking is that the first tattoo Logic ever got, "happy wife, happy life," was inspired by Andrea. He got the ink before tying the knot with Andrea, because he "just knew."

"I loved the woman that I was with and I felt really good about that because as much success that you can have, or money, financially being stable, amassing fans, millions of people who know who you are, it is all nothing without someone to share it with," he told GQ.

The Imagine Dragons front man and Volkman ended their relationship after seven years of marriage and three children together.

"After seven beautiful years together, Aja and I's marriage has come to an end," Reynolds wrote on Twitter. "Our children continue to be the most important thing in our lives, and we will continue to co-parent them with all our love," Reynolds wrote on Twitter in April.

"Aja is the reason that I am anything today," the singer told Ellen DeGeneres a few months later. "All activism in my life, all musical accomplishments come from her. She's my best friend. She's been my creative partner for 10 years now, and hopefully for the rest of my life."

"This is one of my best friends in the whole world and favorite people on the planet," Grande wrote on her Instagram story at the time. "I respect and adore him endlessly and am grateful to have him in my life in any form, at all times regardless of how our relationship changes or what the universe holds for each of us!"

People who have followed the couple's relationship for 14 years were blindsided by their breakup.

In a joint statement, they clarified that "there has been no lying or cheating or fighting that prompted this change, just an expansion of our individual evolution which has inspired us to support each other in a new way."

"This difficult decision comes after thoughtful, respectful consideration," they told People. "Even though we are parting as a couple, we're very much committed to remaining friends and we will continue to support each other."
